1.2 Use & Restriction. Employee acknowledges that Employee will have access to and be provided with Confidential Information in connection with performing services for Company. Employee expressly recognizes that the efficacy and profitability of Company and its owners and Affiliates is dependent in part upon Employee’s protection of the Confidential Information. Employee may use the Confidential Information solely in connection with performing services for Company and its owners and Affiliates. To ensure the continued confidentiality of the Confidential Information, Employee agrees to hold the Confidential Information in strict confidence. Employee shall not, either during Employee’s relationship with Company, or for such period as such information remains Confidential Information after termination, disclose or use for Employee’s own benefit or for the benefit of any other individual or third party, directly or indirectly, any of the Confidential Information, except as such disclosure or use is expressly authorized by Company in writing. Employee hereby agrees to adhere to the method and form of protection of Confidential Information required by Company, subject to change at Company’s sole discretion. Employee shall not communicate any Confidential Information, even in furtherance of Company’s business, to any individual or third party not privy to the Confidential Information, without express consent by Company and the individual or third party’s agreement to be bound by confidentiality terms that adequately protect Company’s Confidential Information.

1.3 Exceptions. The confidentiality and restriction on the use of Confidential Information under this Agreement shall not apply to Confidential Information to the extent that such Confidential Information: is now, or hereafter becomes, through no breach of this Agreement by Employee, generally known or available to the public; was known to Employee without an obligation to hold it in confidence prior to the time such Confidential Information was disclosed to Employee by Company; is disclosed or used, as applicable, with the prior written consent of Company and in accordance with any limitations or conditions on such disclosure or use that may be imposed in such written consent; or was or is independently developed by Employee without any use of or reference to the Confidential Information. In addition, notwithstanding any other language in this Agreement to the contrary, Employee understands that Employee may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (a) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney if such disclosure is made solely for the purpose of reporting or investigating a suspected violation of law or for pursuing an anti-retaliation lawsuit; or (b) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal and Employee does not disclose the trade secret except pursuant to a court order.

1.4 Required Disclosure. The confidentiality obligations under this Agreement shall not apply to Confidential Information to the extent that such Confidential Information is required to be disclosed pursuant to the order or requirement of a court, administrative agency, or other authority, or otherwise by operation of applicable law.

1.5 Other Nondisclosure Agreements. In the event that Company is subject to the terms of any confidentiality or nondisclosure agreement relating to some or all of the Confidential Information that imposes greater restrictions on the disclosure and/or use of such Confidential Information, then Employee shall comply with such greater restrictions to the extent that Employee is made aware of them in advance and in writing.

4. Injunctive Relief

In the event of a breach or threatened breach of any covenant in Sections 1, 2, or 3, Employee agrees that Company will be irreparably harmed, that money damages alone cannot adequately compensate Company, and that Company shall be entitled to temporary and injunctive relief as well as all applicable remedies at law or in equity available to Company against Employee including, if the Company is the prevailing party in an action to enforce the terms of this Agreement, reasonable attorneys’ fees and costs incurred in bringing any action against Employee or otherwise enforcing the terms of this Agreement.
